Food Processor optional

Ingredients

Crust

2 1/2 cups all-purpose flour (we use einkorn) (300g)
1 cup butter, cold * See step 3, if not using a food processor
1/2 cup sugar
1/4 tsp salt

Filling

2 cups sugar
1/4 cup all-purpose flour (we use einkorn) (30g)
1/2 cup lemon juice (fresh is best)
1 tsp lemon zest (fresh is best)
4 eggs
1/4 cup powdered sugar, for dusting

Instructions

Prep – Preheat oven to 350°F.
Mix – Combine the crust ingredients in a food processor (see below for alternate instructions) or with a pastry knife, but the food processor works best. Pulse until butter is fully mixed and the mix holds form when pressed. Press crust into a parchment-lined 9 x 13 pan until well compacted.
Food Processor Free Option – If you don’t want to use a food processor, simply melt the butter and mix all the crust ingredients together in a medium bowl until smooth. Pour into the parchment-lined pan and smooth with a spatula until the crust is evenly distributed.
Bake – Bake for 20-25 minutes, or until the edges of the crust start to brown. Keep the oven at 350°F while you prep the filling and allow the crust to cool for 10 minutes.
Combine – Mix all the filling ingredients with a whisk until fully combined. Pour over the warm crust and bake for 20 minutes or until the filling is firm.
Chill – Remove from oven and cool for 1 hour before lifting the bars out of the pan with the parchment paper. Allow to cool another 1 hour before slicing, OR chill for 2 hours. Dust generously with powdered sugar before serving.

Notes

Ingredients

Like I said, there are only seven ingredients you need to make this recipe (wait, two of them are from lemons… does that count as one or two ingredients?). You probably have everything you need right now, and in just about 2 hours, you can have fresh lemon bars to enjoy and share!

Sugar – Regular granulated sugar is called for in this recipe. While you can use honey or maple syrup, this recipe requires a lot of changes in order to accommodate that much liquid. Instead, if you want to cut down on white sugar, you can use allulose instead!
Flour – We use all-purpose einkorn flour, but any all-purpose wheat flour, or 1:1 gluten-free replacement will work. Avoid using whole wheat or fresh milled unless it is VERY finely milled!
Lemons – Used for both their juice and zest, fresh lemons work best! Bottled juice and dried zest will be ok, but the flavor will be mild in comparison to fresh. Usually one lemon will produce about 2 tsp of lemon zest. You’ll need at least three lemons for the fresh lemon juice in this recipe anyway.
Salt – We like a high-quality sea salt, but use what you have on hand.
Eggs – Whole eggs are called for, and there is no replacement for these, as they form the creamy custard base for the lemon filling!
Powdered Sugar – Optional, but I like to dust the top to cover all the little holes made from air escaping the filling during baking! You can use regular white powdered sugar, or maple powdered sugar if you prefer a less processed option!
